Description

Keep your telescopes, smartphones, tablets, GPS systems, cameras and other USB-powered devices charged and ready with PowerTank Lithium LT—the ideal outdoor portable-charging solution. Celestron specially designed this product with the needs of amateur astronomers in mind; it’s packed with useful features. First, you’ll find a 12V connection for your Celestron telescope—no cigarette lighter port needed. Once your telescope is connected, attach the battery securely to one of the tripod legs with the included Velcro straps so it is safely out of the way. One USB port keeps your other devices charged, and can be used simultaneously with the telescope charger. When you’re not observing, keep this battery charged and at the ready for unexpected emergencies. PowerTank Lithium LT’s unique Nickel Manganese Cobalt Oxide chemistry which delivers a steady charge over long periods and requires less maintenance than a traditional sealed lead-acid battery. It will last you many times longer thanks to its un-recharged shelf life of 10 years and 2000 charge cycle lifespan. But most importantly, the PowerTank Lithium LT can withstand higher temperatures than standard lithium cobalt batteries and will not be a fire danger if accidentally punctured. All this combined with its rugged design make PowerTank Lithium LT the perfect outdoor power supply.

    • A very reliable CELESTRON battery pack to carry for your telescope.
This is a must have for your evening of viewing the sky. The battery pack is easy to carry and attach to your scope. This lasts many hours. The level indicators are easy to see and the charging time is quick. The value of this is first the price and no more buying AAA batteries that do not last. When you are in the night you want power to light the scope. ... show more

    • Much better than expected.
I regularly use lithium charging packs, so was expecting this to be similar. It’s not. It’s much beefier/bigger. It is powering a Celestron motorized telescope and since December 25, 2024 until January 17, it’s still at 3 of 4 bars charged on its initial charge. We’ve used the telescope regularly (the new hasn’t worn off yet), and have left it on tracking the moon or planets for hours. It’s well worth the money compared to installing and replacing batteries on the tele. Highly recommend. ... show more

    • Works as should
Works as should. Great for my telescope. And as a battery for recharge on trips for kids.

    • Powers my GEM28
I like the fact that the power is regulated. It powers my GEM28 with a Skywatcher150 with no issues. It lives up to the design claims. I'd recommend it for any similar mount configuration.

    • The description for this power tank needs to be improved
This power tank probably works great for what it's designed to do. The problem is that it isn't designed to do what I need and didn't have enough information in the description for me to know that until I received it and read the manual. The manual states that it will provide up to 2 amps service and will shut off if a sustained draw over 2 amps is used. My astrophotography equipment is going to be drawing nearly 10 amps at times, so this power tank will not work. I had to return it. Too bad the description online didn't tell me this before I purchased it. ... show more

I didn't want to mess around with AA batteries, so when I purchased a Celestron NexStar 90 SLT, I picked up this Powertank and am very happy I did. Powers my lighter weight payload OTA with plenty of power to spare. I had it out for the third or fourth time recently and spent an hour or more observing the moon and the power reserve meter didn't diminish at all. Still 4 out of 4, despite this being the second short session in a month without recharging. I'll recharge soon, just to help keep the battery conditioned. Time will tell, but I believe this will hold up for long hours powering my rig. I'm attaching some shots this battery helped me capture. Happy Sky Watching! ... show more

    • Much more convenient and powerful than the lead-acid battery Power Tank.
I bought this battery to replace the Celestron Power Tank that I had for over 10 years. That model used a lead acid battery, and it had two USB ports, along with a very bright LED flashlight. Unfortunately, it quit holding a charge. I decided to buy this model because it is smaller, more convenient, and it holds a charge far longer than the previous model. In a recent trip to Joshua Tree National Park to observe the Milky Way, I used this Power Tank to power my telescope, and it performed flawlessly. In fact, I had forgotten to charge it the first night, and it still had plenty of juice leftover for the second night. I highly recommend it. I hope this review helps. ... show more

    • Great battery!!
I needed a power supply for my Celestron Nexstar 5SE. I thought about getting something with more utility outside of powering a telescope, but decided that I should keep it simple. Plus this has a USB port, which is the most you can ask for without spending $200+ and hours researching trying to find the best battery. I charged it to 100% when I got it about 2-3 months ago. Sadly, it has been extremely cloudy for most of that time and I haven’t been able to use my scope very much. From the time that I’ve had it, this battery has probably been used for 10-12 hours. I just checked it, and I still have 3/4 of the battery indicator lights on! I may have charged it for a minute a while back, I can’t remember. But I’ve used it for hours at a time and never came close to running out of power. Honestly, I think it’s impossible to run out of juice in one night. Great product!! My ONLY gripe is with the strap. It’s too big for the tripod!! It slides down easily. It’s a problem that can be solved, but I don’t see why Celestron would make a strap that doesn’t work with its tripod. ... show more
